The Dutchman’s appointment as manager on Monday truly marks the end of the glorious Alex Ferguson era. Never again will we see that kind of longevity or continuity. Ferguson had ruled Britain's biggest club with a rod of iron from 1986 to 2013, winning everything in sight including 13 English Premier League titles and two European Champions League crowns.

From the heights of achievement to the despair of fallen idols, it has been a game of two halves for sport in 2013.

Rafael Nadal, Andy Murray and Serena Williams led the way on the tennis court, but sports fans saw heroes such as Lance Armstrong and Oscar Pistorius taint their considerable legacies beyond redemption.

Then there was a farewell to one of the giants of football, Alex Ferguson, who left behind a wealth of memories not just for supporters of his club Manchester United but for the beautiful game as a whole - which has suffered through controversies over corruption and future World Cups.

So what was your top sporting story of 2013? CNN's World Sport anchors share their leading selections below, and we'd like to hear your opinions too. FULL POST

His detractors likely won't want to hear this but reports of David Moyes' Old Trafford demise are extremely premature. In fact, those expecting the Scot to fall flat on his face while occupying arguably one of the biggest jobs in club football are in for a rather long wait!

On Saturday I watched first hand as the reigning English Premier League champions recorded their first home league win – a 2-0 victory over newly promoted Crystal Palace – under their new head coach. It wasn't pretty but it didn't need to be.

As the legendary Alex Ferguson himself looked on from the Directors' box, Moyes spoke of his "relief" that three points had been secured with relative ease. He was also presumably very happy indeed to move on from the ridiculous over-reaction to his team's first and only defeat of the new season so far, a narrow one-nil reversal at arch -rival Liverpool.

New York Yankees president Randy Levine, MLS chief Don Garber and Manchester City CEO Ferran Soriano revealed the new franchise plans.

Major League Soccer prides itself on its rapid expansion. And with good reason. Just eight years ago, there were only 10 MLS teams alive and kicking.

That tally will now rise to 20 with the all-new Nycfc set to debut in 2015. But does their arrival on the scene spell double-trouble for the league and are MLS fans as a whole being short-changed by it all?

There’s no doubt that relatively-speaking these are boom times for the soccer scene in the States. Attendances overall are up. Just go to any Portland or Seattle home game and you’ll witness a vibrant, passionate crowd that would put a lot of their European counterparts to shame.

MLS is a sound business model and very much on the right track but I just can’t help wondering to what extent the proposed New York City FC multi-million dollar deal might be risky business.

Sound financial planning has always been key to the league and its mantra but the rule-book went out the window to some degree when David Beckham signed on with the L-A Galaxy seven years ago.

The stringent salary cap was relaxed and in came the three-designated players rule. Now think about it for just a moment. Would that really be enough for the new franchise’s owners? Remember who they are after all! Manchester City belong to Sheikh Mansour and as a club – in terms of spending prowess- money is truly no object - and he will demand success.

And what should we make of the Yankees involvement in all this? I still recall their marketing tie- in with Manchester’s “other” club United back in the early 2000s. It didn’t last and there always seemed to be a lack of clarity over how it all worked?

Will things be different this time around? It would appear so and that can only be good news for City who’ll be benefit from the Yanks’ stature and local clout.

As I understand it- the most famous brand in baseball will be part-owners and will certainly have a huge say in vital issues like where in fact the new club will play but again we're left wanting to learn more about what exactly their role will be.

I have to conclude this is a great news for footy fans in the New York City area but what about the rest of the country?

The Red Bulls' average home attendance already falls well short of its 25,000 capacity and the Big Apple also has the reformed New York Cosmos on the scene too.

Is this potentially soccer over- saturation New York style? I realize it's the allure of the lucrative Nyc market and all that but has the league missed a great opportunity to truly put new meaning into the word " expansion"?

For example- take the huge area of land known as the Southeastern USA. Not an MLS franchise in sight.

Why? Where I live in Atlanta I'd have to travel some nine hours by car to go and watch my "local" team- DC United in Washington!

Having grown up in North West England- the City fans I know would never have dreamed of seeing the day their club would launch a spin-off franchise in the United States - with the added benefit of being able to loan out players to the MLS side.

Most I'm quite sure would rather the club be fully focused on prioritizing the search for a new manager or improving their woeful recent Champions League record.

In fact- they might even be wondering if they'll possibly even get to see Yankees baseball at the Etihad some day!

I have no doubt the MLS' newest franchise will soon become the league's undisputed super-power backed by the world-wide might of City and the Yankees.

I'm left with this nagging doubt though. Will the other 19 be able to seriously compete? If so, how? The MLS landscape has changed rather dramatically now and it all seems to have happened quicker than a New York minute.
